This early-stage study uses virtual reality tasks to check how well a person can move and function using their eyesight. It may help researchers measure vision abilities in a way that could guide future care for retinal disease.
Bethesda, MarylandAges 5–120 - NCT04289142RecruitingPhase 4
Testing memory effects of dexmedetomidine during heart surgery
This study looks at how a sleep medicine called dexmedetomidine affects thinking and memory after heart surgery. It compares cognitive outcomes over time to see if this sedation choice changes long-term brain function.
Vancouver, British ColumbiaAges 60 years+ - NCT04291651Recruiting
Pancreatic Cyst Registry for Adults With Pancreatic Cysts
This registry study collects information from adults who have a pancreatic cyst (a fluid-filled sac in the pancreas). It may help doctors understand these cysts and how they change over time, which can improve future care.
San Francisco, CaliforniaAges 18 years+ - NCT04299828Recruiting
Study of inflammation activity during complex heart surgery
This study measures how active white blood cells and inflammation are during complex heart surgery using a heart-lung machine. It may help doctors better understand what triggers inflammation during surgery and how to improve care.
Boston, MassachusettsAges Any age - NCT04304898Recruiting

Rotterdam, South HollandAges 18 years+ - NCT04307615Recruiting
Oxygen versus CPAP during emergency lung fluid episodes
This trial tests whether regular oxygen or CPAP (a breathing-support machine) works better for people who have swimming-induced pulmonary edema, a sudden buildup of fluid in the lungs after swimming. It may help doctors choose the safest and most effective breathing treatment in an emergency.
FalunAges 18 years+ - NCT04310930RecruitingPhase 2/Phase 3
Find the best treatment plan for a lung infection
This study looks for the best way to treat Mycobacterium abscessus (MABS), a difficult lung infection. You may join a treatment group, or first join an observation group and possibly move into treatment later if you meet the criteria.
Kogarah, New South WalesAges Any age - NCT04312633Recruiting
Testing a new throat biopsy mapping method for Barrett’s disease
This study follows people for 5 years to see how well a new biopsy-mapping test (WATS3D) works during routine upper endoscopy. It may help doctors find Barrett’s esophagus changes earlier and better guide follow-up after treatment.
Bethpage, New YorkAges 18 years+ - NCT04321512Recruiting
Blood test study for people with heart or stroke problems
This study looks at a type of white blood cell (monocytes) in blood to understand differences in people with certain heart attacks, stable heart disease, or ischemic stroke. It may help researchers learn why these conditions happen and how the immune system may be involved.
Farmington, ConnecticutAges 18 years+ - NCT04322734Recruiting
Blood tests study immune and metabolism markers in neurodevelopment
This study looks for biological “signals” in blood—related to the immune system and metabolism—to better understand conditions like autism and other brain or development-related disorders. It may help researchers find markers that could guide future diagnosis or treatment.
Phoenix, ArizonaAges Up to 18 years - NCT04330287Recruiting
Study of heart health in adults aging with HIV
This study looks at how aging affects heart health in people who have HIV. It may help researchers find better ways to prevent or monitor heart problems over time.
Essen, NordrheinwestfalenAges 18 years+ - NCT04330729Recruiting
Aspirin effect on blood clotting in kidney disease
This study checks how aspirin (also called salicylate) affects how platelets work, which helps blood clot. It involves people with advanced chronic kidney disease who are treated with Aranesp, and it may help guide safer care.
RoskildeAges 18–85 - NCT04333706RecruitingPhase 1/Phase 2
Sarilumab plus capecitabine for certain breast cancers
This trial studies whether adding sarilumab to capecitabine can shrink or control metastatic or high-risk breast cancer that lacks HER2 and is either triple-negative or hormone-resistant. It aims to find a safe dose first, then look at how well the treatment works compared with historical results.
Los Angeles, CaliforniaAges 18–99 - NCT04338048Recruiting
Study for autosomal dominant polycystic kidney disease
This study enrolls people who have been diagnosed with autosomal dominant polycystic kidney disease (ADPKD), a genetic kidney condition that can cause kidney cysts. It aims to learn about this specific form of the disease so better care is possible for the right patients.
Washington D.C., District of ColumbiaAges Up to 18 years - NCT04339777RecruitingPhase 2
Bone marrow transplant for inherited immune system disorders
This trial studies how well a donor bone marrow (stem cell) transplant works for people with inherited immune system problems (called immune deficiencies). It’s for patients who haven’t improved with usual treatment or don’t have another good option.
Bethesda, MarylandAges 4–69 - NCT04354545Recruiting
Testing treatments for eye discomfort in glaucoma
This trial studies how to treat eye surface discomfort in people who have glaucoma and are already using multiple eye drops. It may help reduce symptoms like irritation while keeping glaucoma treatment on track.

Study of thinking changes in older adults
This trial looks at people over age 50 who have mild thinking or memory problems but do not have dementia by standard clinical criteria. It tests how these early changes are characterized and measured using exams such as blood tests and brain scans, which may help improve understanding and future care.
Guangzhou, GuangdongAges 50 years+ - NCT04365855Recruiting

Common questions
- Are there clinical trials for disease?
- Yes. Clin2 currently lists 9,583 recruiting disease studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a disease trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a disease trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
